Held in 27 towns and cities across the country, the week-long series of conferences, talks and school visits, organised by lobby group NZTech, will be the country's biggest tech festival ever.

With technology and innovation now New Zealand's fastest growing and third biggest industry, Techweek aims to promote the country as an Asia Pacific tech hub.

"New Zealand is developing a bit of a reputation in areas such as agritech, artificial intelligence, blockchain, augmented reality and the Internet of Things," NZTech chief executive Graeme Muller says.

"Techweek is also about getting the kids of New Zealand involved."

Mr Muller says an upcoming workshop in which Wellington kids instruct Members of Parliament on how to write computer code will be a particularly fun event from among the 258 activities planned.

Another event Mr Muller is looking forward to is the Future Realities Conference at Queen's Wharf in Wellington on May 10.

During Future Realities, leading Kiwi tech gurus will talk about how they see technology changing the way New Zealanders live, work and play.
